Opened an assembly,

• 6 identical fasteners, (same part number same original file location) don't show in graphic view,
• In tree they show a warning and appear grayed out
  • The warning is "The file for this component has a non matching internal ID"
• I can resolve the first, but no others,
• This is not relegated to this part or this assembly only I have 4 other different parts (3 are screws, 1 is a hole plug)
• any ideas?
